    debug: Enable cache flushing after every operation
    
    If DEBUG_FLUSH_CACHES is enabled then emit a MI_FLUSH after every
    rendering operation. This is intended to 'fix' cases where we are
    missing a required flush in the middle of a sequence of operations, such
    as switching between 2D to 3D and render to sampler.
